AMHIS Hail Swath Mapping
See the full damage corridor, not just the point
AMHIS clusters sequential hail reports from the same supercell into oriented ellipse swath polygons aligned to storm motion — revealing the entire path of destruction across hundreds of square miles. Indispensable for property professionals, insurance assessors, and roofing canvassers.

Core Capabilities

Everything you need to
see the storm clearly

Powered by AMHIS — Patent Pending 64/027,247 — combining AI, atmospheric physics, and real-time open-source weather data.

🎸
3D Hail Strike Mapping
Precise hail report points rendered as 3D extruded pillars — height and color scaled to hail size. See exactly where hail landed down to street level, from pea-size to baseball and beyond.
DPKEE Physics
🌟
Hail Swath Visualization
AMHIS clusters sequential hail reports from the same supercell into oriented ellipse swath polygons aligned to storm motion — showing the full damage corridor, not just point locations.
Storm Clustering
🌪
Tornado Track Animation
Consecutive tornado reports connected into animated track paths with glowing halos — instantly showing storm direction, speed, and affected corridor with precision timing.

Patent-Protected Technology

Built on a foundation of
proprietary AI innovation

AMHIS integrates five patent-pending technologies into one unified platform. App. No. 64/027,247.

AI & Machine Learning Engines
VSTE
Volumetric Swin Transformer Encoder
3D atmospheric volume analysis using transformer architecture to identify hail embryo formation and supercell rotation signatures from multi-layer radar data.
DPKEE
Dual-Polarization Kinetic Energy Estimator
Real-time terminal velocity and kinetic energy calculation for hailstones of any size using dual-pol radar differential reflectivity signatures and AMHIS physics models.
PSDM
Probabilistic Spatial Diffusion Mapper
Bayesian spatial propagation model that predicts hail swath extent and tornado path continuation probability with confidence intervals updated in real time.
CVFL
Continuous Validation Feedback Loop
Automated accuracy scoring against SPC storm reports and NWS damage surveys — continuously improving prediction models with each storm cycle.
Platform Architecture
STORM BRAIN
AMHIS Storm Brain
Stateless risk assessment engine computing per-city Composite Severe Weather Index (CSWI) from SPC outlooks, storm reports, NWS forecasts, and dual-pol radar analysis.
MAP BUILDER
AMHIS Map Builder
Converts raw weather data into precision GeoJSON: 3D hail extrusion pillars, oriented swath ellipses, tornado track LineStrings, and SPC outlook polygons — all live.
WEBSOCKET
Real-Time WebSocket Feed
Persistent WebSocket connection pushes storm updates, new alert broadcasts, and risk matrix changes to every connected client within seconds of data availability.
